Extra 5: Almoravids FP+T support

Extra 5 shows "T support units" for some FP options . Could these "T support" units count for maximum/minimum?

For example:

4-20 FP Berber foot or Black Guard
+ T Support archer unit

So 2 FP and 2 T support count as "4 units" for that mínimum (4)?

I think those support units work as an "additional improvement" as "The Hundreds", or similar S supports for cavalry units. So those T support units must not count for mínimum.

Correct about the FP+T combinations. 2 large units equals 4 units for the minimum.

Sure? And what about Late Andalusian list (Extra 5)? You can form Large Units of FP andalusian infantry with T archers. Must be counted for FP andalusian foot maximum? Or for T maximum?

Both I would imagine.
